MEANS FOR MEASURING AND MIXING LIQUIDS.

certain new and useful Improvements in Means for Measuring and Mixlng Liquids, of

which the following is a specification,

My invention relates to apparatus for automatically measuring, mixing and delivering a carbonated liquid such'as water mixed with a flavoring liquid such as a flavoring syrup in determinate or measured proportions, and is especially designed for use in dispensing soda water, ginger ale and other drinks. I

The object of my invention is to provide a simple, cheap and effective apparatus by means of which the two liquids making up the drink shall be delivered or dispensed in the desired fixed proportion without variation due to the tendency ofthe carbonating gas to accumulate in the measuring chambers or from differences in the viscosity of the flavoring syrup or liquid employed as one of the ingredients of the drink.

To this end, my invention consists in the combination of valves, piston measuring cylinder, and a pair of measuring cups for the flavoring liquid in which the various parts are combined in a manner hereafter more particularly described and claimed.

In the accompanying drawings, Figure 1 is a front elevation and partial vertical section through the supporting frame of so much of an apparatus embodying my invention as is necessary to disclose its manner of construction and operationf Fig. 2 is an end elevation of the apparatus on a reduced scale, the supportingframe being indicated in section on the line X X, Fig. 1 and illustrates that portionof the apparatus which contains the piston measuring cylinder hereshown'in-seetion. Fig. 3 is a similar view from the other end and shows the measuring cups, asection of the frame being taken on the line Y, Y, Fig. 1, one of the measuring cups being shown in section.

the apparatus looking at the piston measuring cylinder end.

A indicates the valve or faucet carrying shaft of the apparatus and B suitable frameworkupon which the parts are mounted.

The manner and means of operating this shaft form no particular part of myinvention, but I have, for the sake of illustration, shown a shaft as provided with a coupler C provided with slots adapted to receive the coin of proper size and tosupport the same in the path of a manually operated actuated device after the manner described in patent to J. P. Muth, dated June 14 1904, No. 862,429.

The coin chute and opening through which the coin is delivered to the coupler are merely indicated. The manual operating device is typified by a loosely mounted lever C mounted on shaft A and provided with a )rojection adapted to engage the coin,therey coupling the lever and shaft A, as more particu arly set forth in the patent above referred to.

The faucet may consist of two separate valve structures.

E, E indicate the valve casings for the two separate valves which may be both mounted upon said shaft so as to be actuated together when the shaft is turned. The

valves themselves may be constructed in any suitable way as, for instance, in the manner indicated in Figs. 4, 5 and 6. Each valve, preferably, comprises within the cas-'- ing a disk E seated on one face against a plane face of the valve body which latter is provided with suitable ports 6, e e e adapted to register with appropriate ports in the disk E said latter ports being connected in the body of the disk by suitable passages as indicated by the dotted lines in the Figs. 2 and 3 and inFig. 6. This construction provides a four-way valve whose connections may be reversed by a quarter turn.

The valve whose casing is indicated at E controls the connection between a suitable source of charged liquid such as carbonated water under pressure and the opposite ends of the measuring cylinder D which measures the carbonated liquid and contains a mov' able piston, and also the connections from the opposite ends of said cylinderto the discharge pipe leading to the dispensing nozzle.

(2 leads from the source of charged carbonated liquid and port e connects by a pipe f with the discharge or outlet; pipe F into which leads also a pipe connected with a corresponding port of the valve whose casing is indicated at E.

As already stated,the cylinder D is provided with a movable piston. The liquid passing into one end of said cylinder forces the piston to the opposite end thereof and when the piston stops the cylinder contains the desired measured quantity of liquid which obviously can be forced out of the cylinderby the application of pressure to the piston at the. opposite side thereof. By the operation of the valve controlling the connections of measuring cylinder D, the exact uantity ofcarbonated liquid required for a rink is measured by permitting the liquid to flow into one end of the cylinder D 3 until the piston therein is forced to the opposite end of the cylinder. During such operation the c e'ction between said opposite end of thezg l inder and the discharge nozzle is open so. that the liquid previously meas-- q ured out into the cylinder by connection .of

the source of carbonated liquid with such opposite end is forced out into the discharge pipe. Upon turning the valve .the connect ions are reversed and liquid is now meas- 40 ured into the end of the cylinder to which .thepiston has been forced as justdescribed and moves said piston to the starting end, thereby forcing out the contained liquid measuredtherein to the discharge pipe,the

I connection of such end of the cylinder with the source of carbonated liquid being at such time out ofl by the operation ofthe valves. W The action -in detail would be as follows:

. The valve whose casing is indicated at E" has similar ports to those already described but its port a connects with a tank coni taining the flavoring-syrup, while its por'ts 'e and e connect respectively with a pair of measuring cups D having air vents d and the operation of the valve places said cups alternately in connection with the syrup supply and alternately discharges them, the liquid measured in said cups being permitted to pass from the "valve through pi ,e'

f tothe discharge-pipe F into-which't e carbonated liquid from measuring cylinder D is simultaneously delivered under pressure by way of anejector nozzle 2 arranged as 5 shown at or near the point of discharge of pipe f into pipe F so as to operate by an ejector process to exhaust or forcibly pull the flavoring syrup or liquid from that one of the measuring cups being discharged, and at the same time produce a thorough mixture of the syrup and carbonated liquid.- The end of pipe f, Fig. 2, is reduced as shown in Fig. 3 to form this nozzle. During such discharge of one measuring cup, its'connec- 'tion is cut off from the source of syrupsupply and the other cup, being connected. with such source, is filling. It then becomes possible to draw two drinks immediately in succession without waiting for the refilling of a cup which has been discharged asafter one cup has been emptied the valve is operated to draw another drink and. the ports connect with the other cup which was filling while the first one was emptying, the passages between the source of syrup supply and the measuring cups obviously being of sufficient size so that one measuring cup will fill in the length of time the other takes to empty.

Assuming that the apparatus is employed for dispensing ginger ale, the one valve would have its port c connected with the tank of carbonated water and the other would have a similar port connected with a tank of ginger ale syrup. The combined contents of measuring device D and one measuring cup D exactly equals the amount of ginger ale required for one drink; The two valves being in position shown in Figs. 2 and 3 respectively, the carbonated liquid 'will flow through port e to one end of the cylinder D and the syrup will flow to the right hand cup D while at the same time the carbonated li uid will flow from the opposite end of the cy inder'D through port 0 and from the l'eft-hand measuring cup D .to the. outlet pipe f. The carbonated liquid assing the nozzle f will aid in drawing 0 the syrup from the left hand cup D, which syrup drops down just behind the end of the nozzle f 2 and is sucked along not all at once but gradually so that the combined liquids are discharged into the drinking glass in mixed condition. By this operation of the valve, the ports have been brought to regisamount of syrup in the other measuring cup D and of carbonated li uid in the opposite end of the cylinder-D and such quantities are ready for simultaneous discharge by the next operation of the valve mixed in their measured proportions. I

' In order to avoid the necessity of stuffing boxes around the shaft A and to make it possible .to employ any desired number of valves on the same shaft, I prefer to employ the 'manner of packing the valve illustrated in detail in Figs. 4, 5 and 6 in which G indicates a ring or disk of leather or other suitable material mounted .on that faceof the valve body 'ter in a manner to measure the appropriate the valve body.

spout.

or casing against which the face of valve disk apparatus differs from. such previous con- E presses. Said ring G may be held in place stru'ctions as hm'einbeforo set forth and secures an unwarymg proportion of the two by appropriate pins g and is of course perforated at points coincident with the ports in The valve disk l5" is provided with annular metal ridges 71, which are concentric with one another and engage the ring G on annular lines within and without the circle embracing the valve ports. To seat each disk firmly, an adjusting sleeve K may be employed for each, said sleeve being threaded to engage a screw thread in the head of the casing and being arranged. to engage the outside face of the disk and being held by a lock nut L. the valve disk press iirmly against the leather or other washer and produce aliquidtight joint which prevents escape of the liquid in an improper way from one port to another or from the ports to the central shaft A, which, therefore, requires no packing.

The shaft A passes freely through the valve body as indicated, but the disk E is held against rotation on the shaft by a suitable spline which will'permit the longitudinal adjustment of the disk for the purpose of taking up wear and insuring a good liquidtight joint at the packing ring G. The pins 9 prevent the turning of the ring G uponthe seat.

By the use of my apparatus, I not only socure the discharge of a fixed or unvariable amount ofcarbonated liquid owing to the fact that the quantity measured is determined exactly by the cubic capacity of the measuring cylinder no matter how long the interval between the operations of the valve shaft, but I also make it possible to draw one drink immediately after the other with the desired or required. amount of flavoring syrup, thus securing at all times an exact proportion of the liquids which go to make up the drink.

I am aware that it has been before proposed to employ faucets for carbonated beverages in which provision is made for delivering a carbonated liquid and flavoring syrup in mixed condition, but in some of such previous forms of apparatus, the carbonated liquid has been measured by allowing it to flow into a receiver closed at one end and then' to discharge therefrom through the inlet passage so that there is an opportunity for the collection of gas at the top of the receiver and-the quantity measured 0H will vary.

In otherforms of apparatus the syrup is measured in a measuring cup and is delivered together with an unmeasured quantity of the carbonated liquid through the delivery In the latter form of apparatus but one measuring cup is used for each desired syrup and the construction issuch that the measuring of a fresh quantity cannot begin until thepreviously measured quantity has been completely drawn off. My improved The annular ridges on liquids, while at the same time permitting drinks to be dispensed in immediate succession.
